  [摘要] 目的 研究胱抑素C和炎症因子在预测2型糖尿病并发肾病中的价值。方法 选择该院2014年1月―2017年4月收治的2型糖尿病并发肾病患者(T2DM+N)和2型糖尿病(T2DM)患者为研究对象,检测并比较两组研究对象胱抑素C、hs-CRP、TNF-α和IL-6的差异,分析2型糖尿病并发肾病影响因素并研究其预测价值。结果 T2DM+N组2型糖尿病并发肾病患者胱抑素C、hs-CRP、TNF-α和IL-6均显著高于T2DM组2型糖尿病患者(P0.05)。
  1.2 观察指标及检测方法
  T2DM+N组和T2DM组患者均检测以下指标:①胱抑素C:采用胶乳增强型免疫比浊法检测,正常值为0.6~1.2 mg/L;②炎症因子:包括hs-CRP、TNF-α和IL-6,空腹8 h后取肘静脉血,3 000 r/min离心后取血清检测,检测方法为酶联免疫吸附法。
  1.3 统计方法
  采用Sigmaplot 11.0统计学软件进行分析。T2DM+N组和T2DM组患者胱抑素C和炎症因子对比采用t检验,采用多元Logistic回归筛选出危险因素,对危险因素绘制ROC曲线评测其价值。P  胱抑素由?C体有核细胞产生,仅通过肾脏肾小球滤过清除,机体胱抑素C水平仅由肾小球滤过决定,不受性别、年龄及饮食等外界因素影响,是反应肾小球滤过功能最理想的标志物,且在肾脏早期病变时即可检测胱抑素C浓度改变,在评估肾脏早期病理改变及肾功能改变中具有重要价值,灵敏度及特异性高于传统的尿素氮及肾小球滤过率。该研究中,单纯2型糖尿病患者胱抑素C水平正常,而当其并发肾脏病变时胱抑素C水平显著升高,提示胱抑素C在评估2型糖尿病并发肾脏病变中具有重要价值。目前尚无预测2型糖尿病并发肾病的指标,2型糖尿病患者确诊并发肾病时往往肾功能极差,故寻找预测2型糖尿病并发肾病的标志物具有重要临床价值。该研究以是否并发肾病为因变量,以胱抑素C、hs-CRP、TNF-α和IL-6为自变量对T2DM+N组2型糖尿病并发肾病患者行Logistic回归分析,发现胱抑素C、hs-CRP、TNF-α和IL-6为2型糖尿病并发肾病的影响因素(P参考文献]
